Abstract

The energy level of the

{}^{4}S^{o}

state of

{He}^{-}

is found to be lower than that of the

(2 p 2 p) {}^{3}P

state of He by about 0.328 eV. It is metastable against autoionization and decays through radiation to the triply excited autoionization state of

{}^{4}P^{e}

and its associated continuum. For Li and three-electron positive ions, the

{}^{4}S^{o}

state also decays to the doubly excited

{}^{4}P^{e}

bound state. The energy levels of these states are calculated and transition wavelengths are also predicted.
